There are several differences between core electret microphone elements and standard microphone elements in terms of their working principles and characteristics, such as operating principles, frequency response, sensitivity, and dynamic range.
1. Operating Principle
Core electret microphone elements operate based on the principle of capacitance. They contain a capacitor that changes its capacitance value as it vibrates in response to sound waves. This change generates a current variation, converting sound into an electrical signal. On the other hand, standard microphone elements can operate on different principles such as dynamic, electrostatic, or electromagnetic. These principles differ from that of electret microphone elements.
2. Frequency Response
Core electret microphone elements typically have a wider frequency response range. They can capture higher and lower frequencies, offering a more comprehensive and accurate audio representation. In contrast, the frequency response of standard microphone elements might be more limited, preventing them from capturing very high or very low frequencies.
3. Sensitivity
Core electret microphone elements generally have higher sensitivity. They can detect subtle sound changes and convert them into corresponding electrical signals, resulting in clearer and more detailed audio output. Standard microphone elements may have relatively lower sensitivity, limiting their ability to capture and convert sound variations.
4. Dynamic Range
Core electret microphone elements usually feature a wider dynamic range, allowing them to handle a larger variance in sound intensity. They can capture very soft lows and very loud highs without distortion or saturation. Standard microphone elements, however, might have a more limited dynamic range, making them less capable of handling changes in sound intensity.
It is important to note that different brands and models of microphone elements may have unique characteristics. Therefore, when choosing and using microphone elements, one should consider their operating principles, frequency response, sensitivity, and dynamic range based on the actual needs and application scenarios.
